Abstract:

Abstract:
This disclosure relates to methods for isolating bacterial cells, fungal cells, and single-celled parasites present in a blood sample containing higher eukaryotic cells; particularly wherein the microorganisms are present at a concentration significantly lower than the eukaryotic cells in the sample.
Abstract:
The invention provides a method for identifying methicillin resistant Staphylococcus aureus (MRSA) in a bacterial sample comprising the steps: classifying bacteria in the sample as Staphylococcus aureus (SA) and determining the presence or absence of the phenol soluble modulin peptide or a variant thereof wherein the presence of the PSM-mec peptide or variant thereof indicates methicillin resistant Staphylococcus aureus. The variant is preferably the formylated version of the PSM-mec peptide having a mass to charge ratio of 2415 in a singly protonated state.

Abstract:
A method of identification of drug targets and drug resistance mechanisms in human cells of a drug comprising the steps of: generating at least one drug-resistant sample and at least one drug-sensitive sample; analyzing substantial portions of the genome and/or transcriptome of the least one drug-resistant sample and drug-sensitive sample to obtain sequencing data; detecting substantially all alterations in the at least drug-resistant sample; deriving a resistance signature; and performing analysis of the drug resistance signature of at least one recurrently altered gene using bioinformatic tools and cellular biology methods to determine if alteration of the at least one gene of the drug resistance signature is sufficient to confer at least partial resistance to cells or tissues against the drug.
Abstract:
Specific peptides, and derived ionization characteristics of those peptides, from the Bcl-2-like protein 11 (BIM) are provided that are particularly advantageous for quantifying the BIM protein directly in biological samples that have been fixed in formalin by the method of Selected Reaction Monitoring (SRM) mass spectrometry, or what can also be termed as Multiple Reaction Monitoring (MRM). Such biological samples are chemically preserved and fixed where the biological sample is selected from tissues and cells treated with formaldehyde containing agents/fixatives including formalin-fixed tissue/cells, formalin- fixed/paraffin embedded (FFPE) tissue/cells, FFPE tissue blocks and cells from those blocks, and tissue culture cells that have been formalin fixed and or paraffin embedded. A protein sample is prepared from the biological sample using the Liquid Tissue™ reagents and protocol, and the BIM protein is quantitated in the Liquid Tissue™ sample by the method of SRM/MRM mass spectrometry by quantitating in the protein sample at least one or more of the peptides described. These peptides can be quantitated if they reside in a modified or an unmodified form. An example of a modified form of a BIM peptide is phosphorylation of a tyrosine, threonine, serine, and/or other amino acid residues within the peptide sequence.
Abstract:
Provided are methods of detecting the presence and/or amount of methicillin-resistant S. aureus in a sample. The methods may include, in some embodiments, processing the sample with a lysyl endopeptidase followed by amplification and detection of S. aureus chromosomal DNA if present in the sample. The PCR amplification may include the use of one or more forward primers that target SCCmec right chromosomal junction regions, a reverse primer that targets an or fK region and at least one probe that targets and or fX region between the forward and reverse primers. The reverse primer and/or the at least one probe may be targeted to conserved regions of or fX , i.e. regions that do not contain SNPs or other polymorphisms. Sets of oligonucleotides and kits for performing the methods are also provided.
Abstract:
The present invention relates, generally, to methods to identity subjects responsive to p73/p63 targeting agents such as platinum-based chemotherapy agents such as, but not limited to, cisplatin and cisplatin derivatives and analogues thereof. More particularly, the present invention relates to methods to identify a cancer responsive to a p73/p63 targeting treatment, such as chemotherapeutic agents such as cisplatin, by determining if the cancer expresses and/or has the activity of p63 isoforms such as DNp63 isoforms, and expresses and/or has the activity of p73 isoforms such as TAp73 or DNp73 isoforms. The present invention also relates to methods to identify a cancer unresponsive to a p73/p63 targeting treatment, such as chemotherapeutic agents such as cisplatin by determining if the cancer lacks the expression and/or activity of p63 isoforms such as DNp63 isoforms. The invention further provides kits to determine the expression and/or activity of p63 isoforms such as DNp63 isoforms, and/or the expression and/or activity of p73 isoforms such as TAp73 and/or DNp73 isoforms in a biological sample.
